Patent EP-0321862-A2 (EP)
Inventor: DOLHERT LEONARD EDWARD
IPC: C01B13/14
Filed: 1988-12-15
Abstract: Improved process for making superconductors. A powdered peroxide, "MO₂", is admixed with two oxide powders, "L oxide" and "A oxide"; where M is at least one metal of the group Ba, Mg, Ca, and Sr - preferably Ba; O is oxygen; L is at least one metal of the rare earth group, including scandium and yttrium - preferably yttrium; and A is at least one metal of the group Cu, Ag, and Au - preferably Cu. The powdered mixture becomes superconducting when shaped and fired. The peroxide oxygen helps furnish oxygen requirements in the final superconducting composition, e.g., Y₁Ba₂Cu₃O x . Barium peroxide has a relatively low melting point and thus aids in achieving efficient sintering with enhanced homogeneity. The invention process results in new compositions.

Abstract: HIV-directed inhibitors of the natural 2′-5′A antiviral defense pathway, diagnostic procedures and materials, and modalities for treating viral disorders are described. HIV-induced inhibitors of RNase L in patients with lymphadenopathy (LAS), AIDS-related complex (ARC) and acquired immune deficiency syndrome (AIDS) were isolated and identified. Functional 2-5A is not able to activate RNase L in the peripheral blood mononuclear cells (PBMC) in these patients; endogenous dsRNA, especially mismatched dsRNA, activates 2-5A synthetase which results in an increased concentration by endogenous 2-5A.

Abstract: A novel capsule-like medicament and method for producing such medicaments are disclosed. The method provides a procedure for coating solid cores, such as caplets (16), with a first gelatinous coating (304) on one end (110), and then with a second gelatinous coating (306) on the other end (104) which is thicker than the first, to simulate the interlocking halves of a hollow capsule. The second, thicker gelatinous coating (306) can be provided with a single gelatin coating from a bath (38) having a higher viscosity than the bath used to provide the first gelatinous coating (304). Alternatively, the second gelatinous coating (306) can be provided by double dipping to provide layers of gelatinous material or gelatin.

Abstract: A quick connect fluid coupling having a female part and a male part (12) which is insertable into the female part (14) to thereby establish the fluid connection between the coupling parts. A metal spring retainer (62) in the female part engages an outwardly extending flange (72) on the male part upon insertion into the female part to lock the coupling parts together. In addition, a shut off valve member (34) is contained within the female part and is movable between a closed position and an open position. In the closed position, a seal ring (50) in the female part sealingly engages a central cylindrical portion of the valve member and blocks fluid flow through the female part. Conversely, upon insertion of the male part into the female part, the male part moves the valve member to its open position and enables fluid flow through the fluid coupling parts. Simultaneously, the seal ring engages the outer periphery of the male part and fluidly seals the male and female parts together.

Abstract: A mounting arrangement for vibration transducers (14) such as accelerometer sensors particularly suited for adverse environments as may be encountered with machine tool components and the like. A mounting base (72) is permanently fixed to a vibratory surface (12) to be monitored. This cylindrical base (72) incorporates an annular retaining groove (86) formed in its side surface (76) which cooperates with an annular resilient band (88) which is discontinuous to provide ends which, in turn, may be drawn together when the band is constricted by an external clamp (100). The band includes a stud ring (98) which engages the groove (86) of the mounting base (71) and then permits facile engagement of a transducer base (16) having a V-shaped groove (28) configured at the lowermost portion thereof. The retainer ring or band (88) also incorporates a detent ring which engages the groove of the transducer base. A hose clamp (100) or the like then is used to constrict the resilient annular band (88) to drive the transducer (14) into a compressive relationship with the top surface of the mounting base (72). A cable clamp (24) may be employed which serves to retain armor cladding over communications cable (20) emanating from the transducer and is removably retained in position by the hose clamp.

Abstract: A thermal ink ribbon, in particular a thermal carbon ribbon, having a conventional substrate and having a layer formed on one side of the substrate and consisting of wax- and/or plastics-bound fusion ink for producing scratch-resistant markings by subsequent heat treatment, which is characterised in that small non-melting, colorant-containing polymer spheres which melt in a heat treatment following the thermal printing process are present in the fusion ink during the thermal printing process. Such a thermal carbon ribbon can be produced in particular by a method in which an aqueous dispersion which contains the small polymer spheres and fine particles of the binder is applied to the substrate of the thermal carbon ribbon, and the aqueous part of the dispersion is removed in a customary manner. If, by means of the thermal carbon ribbon according to the invention, a symbol is applied to any substrate and this symbol is subjected to subsequent heat treatment which leads to melting of the small polymer spheres, the printed symbol has a different structure, with the result that the symbol is now scratch-resistant. The scratch resistance plays a role in various industrial areas, such as in labels and other recording media.
